[0002] The keel frame is a building material used to support the shape and fix the structure. It is used as the skeleton and base material of the building decoration structure. The keel frame as a whole includes the main keel and the secondary keel. The main function of the main keel is to bear the main gravity of the ceiling and provide a force-bearing surface for the erection of the secondary keel. The main function of the secondary keel is to disperse the load-bearing force surface of the ceiling and provide a force surface for the laying of gypsum boards. The main keel and the secondary keel are connected by bolts to ensure their overall stability.

[0003] Usually the main purlins are suspended from the ceiling, so their positions are fixed. However, due to the different lengths and widths of different gypsum boards, the distances between the purlins are also different. Although bolt fixing can ensure stability, it is more cumbersome to adjust the distance between adjacent purlins. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, an adjustable and fixed ceiling keel frame comprises a main keel 1, which provides the main force. Two mounting hangers 2 are fixedly installed on the upper surfaces of both ends of the main keel 1, and the mounting hangers 2 are used to be fixed to the ceiling. Multiple main keels 1 will be provided during installation, and a secondary keel 3 is provided between two adjacent main keels 1. The length of the secondary keel 3 is the same as the distance between the two main keels 1. A connecting rod 4 is installed on the upper surface of the secondary keel 3, and the connecting rod 4 and the secondary keel 3 are an integrated structure. Multiple connecting rods 4 are fixedly connected by connecting cross bars 5, and the lower surface of the connecting cross bars 5 is against the upper surface of the main keel 1. The main keel 1 provides a certain supporting force for the connecting cross bars 5, thereby indirectly providing a certain supporting force for the secondary keel 3. Blocks 6 are provided at both ends of the secondary keel 3, and multiple clamping grooves 7 are provided on both sides of the main keel 1. The clamping block 6 is clamped in one of the clamping grooves 7.

[0021] In this embodiment, the positioning groove 7 can extend upward to connect with the space above the main keel 1. At this time, when the secondary keel 3 needs to be adjusted according to the size of the installed gypsum board, it is only necessary to move the connecting cross bar 5 and drive the secondary keel 3 to move through the connecting rod 4 until the positioning block 6 is completely located outside the positioning groove 7. Then, the connecting cross bar 5 is moved horizontally so that the positioning groove 7 and the positioning block 6 are located on the same vertical line. Then, the positioning block 6 is positioned inside the corresponding positioning groove 7. At this time, the secondary keel 3 can be installed firmly, and the structure is simple and easy to operate.

[0022] The positioning blocks 6 are fixedly mounted at both ends of the secondary keel 3 , and a connecting transverse groove 8 is provided on the side surface of the main keel 1 . The connecting transverse groove 8 is connected to the interior of a plurality of positioning grooves 7 , and the depth of the connecting transverse groove 8 is the same as that of the positioning groove 7 .

[0023] The connecting transverse groove 8 and the locking groove 7 form a moving path for the locking block 6. The width of the connecting transverse groove 8 is the same as the width of the locking groove 7. When the connecting cross bar 5 is moved, the locking block 6 is moved to the inside of the connecting transverse groove 8, and then the locking block 6 is moved to the position of another locking groove 7. When moving, the secondary keel 3 can be prevented from falling off, thereby ensuring the stability of the secondary keel 3 when moving.

[0024] Both ends of the secondary keel 3 are provided with mounting grooves 9, and a connecting spring 10 is installed inside the mounting groove 9. The surface of the connecting spring 10 contacts the inner wall of the mounting groove 9, which can ensure that the connecting spring 10 is limited to a certain extent during its movement. One end of the connecting spring 10 is fixedly connected to the surface of the positioning block 6, and one end of the positioning block 6 extends to the outside of the mounting groove 9. The top of the portion of the positioning block 6 located outside the mounting groove 9 is arranged in an arc shape. The shape of the positioning block 6 is adapted to the internal shape of the mounting groove 9. An inner groove 11 is provided inside the positioning groove 7, and the end of the positioning block 6 is stuck in the inner groove 11.

[0025] When the locking block 6 is stuck in the inner groove 11, the secondary keel 3 is in a stable state. When the secondary keel 3 is moved upward, since the connecting spring 10 has a certain squeezing force on the locking block 6, a slight upward movement of the secondary keel 3 will not affect the stability of the installation of the secondary keel 3. When the upward pressure is greater than the elastic force of the connecting spring 10, the locking block 6 will squeeze the connecting spring 10, and the locking block 6 is located inside the installation groove 9. Then the secondary keel 3 is moved. When it is located at the position of another inner groove 11, the rebound force of the connecting spring 10 makes the locking block 6 stuck in the inner groove 11.

[0026] The cross-sectional shape of the secondary keel 3 is set to be T-shaped.

[0027] The depth of the inner groove 11 is greater than the depth of the locking groove 7 .

[0028] It should be noted that the utility model is an adjustable and fixed ceiling keel frame. During use, when the secondary keel 3 needs to be adjusted according to the size of the installed gypsum board, it is only necessary to move the connecting cross bar 5, and the secondary keel 3 is driven to move by the connecting rod 4. The inner wall of the inner groove 11 will produce a certain amount of extrusion on the blocking block 6, and the blocking block 6 will squeeze the connecting spring 10. The blocking block 6 is located inside the installation groove 9. At this time, the connecting spring 10 is in a compressed state. Then the connecting cross bar 5 is moved horizontally so that the blocking groove 7 and the blocking block 6 are located on the same vertical line. When the blocking block 6 is in the position of another inner groove 11, the rebound force of the connecting spring 10 makes the blocking block 6 stuck in the inner groove 11. At this time, it can ensure that the secondary keel 3 is installed firmly, and the structure is simple and easy to operate.
